00:00:00,280 --> 00:00:02,960
Speaker 1: Brought to you by the reinvented two thousand twelve Camray.

2
00:00:03,160 --> 00:00:08,920
Speaker 1: It's ready. Are you get in touch with technology? With

3
00:00:09,000 --> 00:00:17,880
Speaker 1: tech Stuff from how stuff dot com. Hello, everyone, Welcome

4
00:00:17,920 --> 00:00:20,200
Speaker 1: to tech Stuff. My name is Chris Pollette, and I'm

5
00:00:20,239 --> 00:00:24,360
Speaker 1: an editor at how stuff works dot com. And sitting

6
00:00:24,520 --> 00:00:28,800
Speaker 1: just a bit across from me is senior writer Jonathan Strickland. Midnight,

7
00:00:29,240 --> 00:00:31,920
Speaker 1: not a sound on the pavement. Has the moon lost

8
00:00:31,920 --> 00:00:37,360
Speaker 1: her memory? She's smiling alone. This podcast will be much

9
00:00:37,400 --> 00:00:40,760
Speaker 1: better than KATS Yes, I should hope, So I'm going

10
00:00:40,800 --> 00:00:45,080
Speaker 1: to listen to it again and again. Anyway, So, yeah,

11
00:00:45,120 --> 00:00:47,639
Speaker 1: today we're gonna talk. We had actually some requests come

12
00:00:47,680 --> 00:00:52,480
Speaker 1: in about explaining thirty two bit versus sixty four bit

13
00:00:52,720 --> 00:00:56,040
Speaker 1: in the terms of computers. What does that mean? What

14
00:00:56,360 --> 00:01:00,480
Speaker 1: is sixty bit automatically better than thirty two bit? What's

15
00:01:00,520 --> 00:01:02,960
Speaker 1: the deal behind this? Because we've seen some operating systems

16
00:01:03,000 --> 00:01:05,880
Speaker 1: come out over the last several years, especially since like

17
00:01:05,920 --> 00:01:10,160
Speaker 1: Windows Vista that had sixty four bit versions and thirty

18
00:01:10,160 --> 00:01:12,960
Speaker 1: two bit versions and not all would work on every computer.

19
00:01:13,200 --> 00:01:16,200
Speaker 1: What's up with that? Anyway? Well, the answers to those

20
00:01:16,280 --> 00:01:22,600
Speaker 1: questions is basically yes, no, maybe it's a computer architecture question.

21
00:01:22,680 --> 00:01:26,000
Speaker 1: As it turns out, so and and the answer is

22
00:01:26,600 --> 00:01:29,520
Speaker 1: is not definitive. I mean it's sort of well anyway,

23
00:01:29,600 --> 00:01:31,800
Speaker 1: let's talk about it. Okay, yeah, so let's talk about

24
00:01:31,800 --> 00:01:34,000
Speaker 1: what it all means to be thirty two bit versus

25
00:01:34,040 --> 00:01:36,640
Speaker 1: sixty four bit in the first place. So, well, that

26
00:01:36,680 --> 00:01:42,120
Speaker 1: part's easy. We're talking about computer architecture here. Now, just

27
00:01:42,240 --> 00:01:44,320
Speaker 1: on a high level, this is going to be very

28
00:01:44,360 --> 00:01:46,760
Speaker 1: general for all of you. So all of you computer

29
00:01:46,800 --> 00:01:49,440
Speaker 1: scientists out there, Uh, you might want to fast forward

30
00:01:49,440 --> 00:01:52,640
Speaker 1: a little bit because your your eyes may start bulging

31
00:01:52,680 --> 00:01:56,160
Speaker 1: if you hear me describe computers in these simplistic terms.

32
00:01:56,400 --> 00:01:59,600
Speaker 1: Make yourself a sandwich. But in general, you have this

33
00:01:59,800 --> 00:02:03,720
Speaker 1: thing in your computer, the central processing unit, all right,

34
00:02:04,040 --> 00:02:09,120
Speaker 1: And they're basically two ways to try and make a CPU,

35
00:02:09,560 --> 00:02:14,080
Speaker 1: uh do more work or or be more efficient. Um,

36
00:02:14,120 --> 00:02:17,120
Speaker 1: and I'm saying basically two ways are actually more than that,

37
00:02:17,240 --> 00:02:20,440
Speaker 1: especially if you go into multi core processing. But if

38
00:02:20,440 --> 00:02:23,680
Speaker 1: you're talking about single core processor, you can either make

39
00:02:23,760 --> 00:02:27,760
Speaker 1: the processor work faster, which means that it can operate.

40
00:02:27,760 --> 00:02:30,840
Speaker 1: It could complete more operations in the same amount of

41
00:02:30,840 --> 00:02:35,960
Speaker 1: time as a slower CPU. Right, So operations are done

42
00:02:36,040 --> 00:02:39,919
Speaker 1: in uh in in uh cycles for a second. So

43
00:02:39,960 --> 00:02:42,400
Speaker 1: how many times the clock cycles per second with that

44
00:02:42,480 --> 00:02:46,200
Speaker 1: particular processor essentially means how many operations that can do,

45
00:02:46,320 --> 00:02:50,560
Speaker 1: although some operations require multiple cycles. Okay, so you can

46
00:02:50,600 --> 00:02:53,600
Speaker 1: make your computer go faster by putting in a faster processor.

47
00:02:53,919 --> 00:02:56,680
Speaker 1: But another way computers can go faster is if they

48
00:02:56,720 --> 00:03:02,359
Speaker 1: can process more information at one time than a slower

49
00:03:02,480 --> 00:03:05,280
Speaker 1: process or a processor that runs at the same speed

50
00:03:05,320 --> 00:03:09,240
Speaker 1: but does less information at the time. Because for a

51
00:03:09,320 --> 00:03:15,200
Speaker 1: processor to to actually execute commands and to crunch numbers

52
00:03:15,880 --> 00:03:19,200
Speaker 1: essentially is what a secret is doing. It's computing. Yeah,

53
00:03:19,320 --> 00:03:23,720
Speaker 1: it's pulling information from the computer's memory and then executing

54
00:03:23,840 --> 00:03:27,200
Speaker 1: a series of commands that are dictated by whatever the

55
00:03:27,240 --> 00:03:30,640
Speaker 1: application that's running says it has to do, and then

56
00:03:30,680 --> 00:03:34,400
Speaker 1: you get the output. All right, So, if you have

57
00:03:34,960 --> 00:03:38,520
Speaker 1: a narrow pathway, then only so much information can come

58
00:03:38,560 --> 00:03:40,960
Speaker 1: through at a time. If you make that pathway wider,

59
00:03:41,040 --> 00:03:43,800
Speaker 1: more information can come in and that same amount of time,

60
00:03:43,840 --> 00:03:47,040
Speaker 1: the information is not necessarily traveling faster, is just more

61
00:03:47,040 --> 00:03:49,240
Speaker 1: of they can go through. So if we use the

62
00:03:49,480 --> 00:03:54,520
Speaker 1: handy dandy, let's talk about a building metaphor that I

63
00:03:54,520 --> 00:03:56,640
Speaker 1: always like to go with. Let's say you've got a building,

64
00:03:57,040 --> 00:04:00,160
Speaker 1: it's got a doorway that's one person wide, and got

65
00:04:00,200 --> 00:04:01,720
Speaker 1: a whole bunch of people who want to go in,

66
00:04:02,360 --> 00:04:04,480
Speaker 1: uh to that building, but they all have to move

67
00:04:04,680 --> 00:04:09,040
Speaker 1: at a specific rate. They cannot run the been the

68
00:04:09,080 --> 00:04:11,760
Speaker 1: hall monitors are there and they're telling everyone no running.

69
00:04:12,760 --> 00:04:14,760
Speaker 1: Then it's gonna take a certain amount of time for

70
00:04:14,800 --> 00:04:17,320
Speaker 1: all those people to get into the building filing in

71
00:04:17,600 --> 00:04:22,279
Speaker 1: single file through that one person wide opening. Now let's

72
00:04:22,320 --> 00:04:25,120
Speaker 1: take that same building, but we've done some reconstruction on it.

73
00:04:25,200 --> 00:04:28,200
Speaker 1: We've made that building so that there are three people

74
00:04:28,440 --> 00:04:32,440
Speaker 1: can walk side by side into that and you still

75
00:04:32,480 --> 00:04:35,160
Speaker 1: tell everyone no running, so they're moving at the same speed,

76
00:04:35,200 --> 00:04:37,760
Speaker 1: but now more people can go into the building in

77
00:04:37,800 --> 00:04:40,560
Speaker 1: the same amount of time as it took. You know,

78
00:04:40,600 --> 00:04:42,560
Speaker 1: you're you're gonna take less time to get everybody in

79
00:04:42,600 --> 00:04:46,280
Speaker 1: than it took for the single person version of that building.

80
00:04:47,000 --> 00:04:50,440
Speaker 1: So that's kind of the idea behind this computer architecture

81
00:04:50,440 --> 00:04:52,960
Speaker 1: with thirty two bit versus sixty four bit at a

82
00:04:53,120 --> 00:04:56,920
Speaker 1: very high level. Yeah, and the thing is, it's, uh,

83
00:04:56,960 --> 00:05:00,760
Speaker 1: there are a number of things that affect U in

84
00:05:00,800 --> 00:05:03,719
Speaker 1: your overall computer architecture. There are a number of things

85
00:05:03,720 --> 00:05:08,159
Speaker 1: that affect how much information can be handled by the

86
00:05:08,200 --> 00:05:11,240
Speaker 1: CPU at a time. For example, you know all the

87
00:05:11,279 --> 00:05:15,200
Speaker 1: different cabling and everything else that's in there. I mean,

88
00:05:15,400 --> 00:05:18,320
Speaker 1: you're if you have a better graphics, faster graphics processor,

89
00:05:18,400 --> 00:05:21,760
Speaker 1: your graphics processor will handle more graphics. But we're speaking

90
00:05:21,800 --> 00:05:26,039
Speaker 1: specifically of the CPU and not of the cables that

91
00:05:26,160 --> 00:05:28,400
Speaker 1: run that information to the different parts of the computer

92
00:05:28,440 --> 00:05:31,800
Speaker 1: and those things. We're talking about the actual processor itself.

93
00:05:32,360 --> 00:05:36,560
Speaker 1: And there is one other thing, however, that uh, that

94
00:05:36,680 --> 00:05:42,000
Speaker 1: it needs to handle this and and that is forgotten

95
00:05:42,040 --> 00:05:49,120
Speaker 1: what it was? What is it? Data bus? Memory? I remember? Now? Well,

96
00:05:49,160 --> 00:05:52,520
Speaker 1: the data bus is the the the pathway between memory

97
00:05:52,680 --> 00:05:56,000
Speaker 1: and the CPU. Well, yeah, that's the thing. See that

98
00:05:56,000 --> 00:05:59,719
Speaker 1: that pathway has to be ample enough to to carry

99
00:06:00,520 --> 00:06:05,120
Speaker 1: uh information. But the memory, the amount of memory you have,

100
00:06:05,800 --> 00:06:10,560
Speaker 1: and how your CPU handles memory is pivotal to how

101
00:06:10,640 --> 00:06:15,240
Speaker 1: well your computer can handle instruction. Yeah. So that's when

102
00:06:15,240 --> 00:06:18,119
Speaker 1: we talk about computer architecture. You're not just talking about

103
00:06:18,160 --> 00:06:21,919
Speaker 1: one component in the computer. If you put a sixty

104
00:06:21,960 --> 00:06:25,440
Speaker 1: four bit processor in a computer and you didn't change

105
00:06:25,480 --> 00:06:29,279
Speaker 1: anything else, it wouldn't matter. It wouldn't matter, Yeah, because

106
00:06:29,279 --> 00:06:31,240
Speaker 1: it because even though you've got a sixty four bit

107
00:06:31,279 --> 00:06:33,400
Speaker 1: processor and there the rest of the computer is not

108
00:06:33,640 --> 00:06:37,080
Speaker 1: designed with the architecture that's necessary to take advantage of that.

109
00:06:37,560 --> 00:06:40,880
Speaker 1: So with the memory, you you know, sixty four bit

110
00:06:40,920 --> 00:06:44,640
Speaker 1: processor would be able to access more memory because the

111
00:06:44,680 --> 00:06:47,200
Speaker 1: sixty four bit that talks about how much information can

112
00:06:47,440 --> 00:06:50,960
Speaker 1: come through, right, and so it's effectively twice as much

113
00:06:50,960 --> 00:06:56,240
Speaker 1: as the thirty two bit. Right, so you've got what

114
00:06:56,600 --> 00:07:00,479
Speaker 1: go ahead, I heard the inhale of stopping anyway. The so,

115
00:07:00,480 --> 00:07:02,920
Speaker 1: so the data bus is it's not a bus like

116
00:07:03,040 --> 00:07:06,680
Speaker 1: get on the bus, you know, or deserts or desert bus.

117
00:07:07,600 --> 00:07:10,200
Speaker 1: It will drive for eight hours and get one point. Yeah, yeah,

118
00:07:10,360 --> 00:07:14,400
Speaker 1: well who Tucson. So yeah, the data bus is essentially

119
00:07:14,400 --> 00:07:16,760
Speaker 1: the pathway from the memory to the CPU. So you

120
00:07:17,400 --> 00:07:20,840
Speaker 1: with a sixty four bit system, you're gonna have more memory,

121
00:07:20,880 --> 00:07:23,800
Speaker 1: more random access memory, more RAM You're going to have

122
00:07:24,200 --> 00:07:27,360
Speaker 1: a larger data bus. The data bus that's the sixty

123
00:07:27,360 --> 00:07:29,480
Speaker 1: four bit data bus that is going to allow sixty

124
00:07:29,520 --> 00:07:33,440
Speaker 1: four bit information to pass through as opposed to thirty

125
00:07:33,480 --> 00:07:36,040
Speaker 1: two bit, and then the sixty four bit processor that

126
00:07:36,080 --> 00:07:39,760
Speaker 1: can process information. This does not work well for every

127
00:07:39,840 --> 00:07:43,280
Speaker 1: kind of computer problem. There are certain kinds of computer

128
00:07:43,320 --> 00:07:47,480
Speaker 1: problems that just don't need that. It's not that, you know,

129
00:07:47,560 --> 00:07:50,880
Speaker 1: it's not that it's harmful, it just isn't beneficial. So

130
00:07:50,960 --> 00:07:53,120
Speaker 1: in other words, let's say that we go back to

131
00:07:53,160 --> 00:07:56,480
Speaker 1: that building example. All right, and let's say that you

132
00:07:56,560 --> 00:07:58,840
Speaker 1: only have one person who has to get in the building. Well,

133
00:07:58,880 --> 00:08:01,640
Speaker 1: it doesn't matter how why the doorway is. If there's

134
00:08:01,680 --> 00:08:04,080
Speaker 1: no obstruction, then that person is going to get in

135
00:08:04,160 --> 00:08:06,560
Speaker 1: the building at the same speed. Whether the doorways one

136
00:08:06,560 --> 00:08:09,920
Speaker 1: person wide or three people wide. Well, same sort of thing.

137
00:08:09,960 --> 00:08:15,600
Speaker 1: If you have a computer application that doesn't require massive uh,

138
00:08:16,480 --> 00:08:19,200
Speaker 1: it doesn't require the CPU to constantly be pulling information

139
00:08:19,240 --> 00:08:23,280
Speaker 1: from memory, then it's not gonna see a big benefit

140
00:08:23,440 --> 00:08:25,880
Speaker 1: to switching from thirty two bit system to a sixty

141
00:08:25,880 --> 00:08:28,960
Speaker 1: four bit system. Oh and I forgot another piece. We

142
00:08:28,960 --> 00:08:31,880
Speaker 1: were talking about computer architecture. With all the physical hardware,

143
00:08:32,120 --> 00:08:34,640
Speaker 1: you also have to have an operating system that can

144
00:08:34,679 --> 00:08:39,360
Speaker 1: take advantage of the sixty four bit architecture. So if

145
00:08:39,400 --> 00:08:41,400
Speaker 1: you have a sixty four bit system, you would need

146
00:08:41,440 --> 00:08:43,400
Speaker 1: to get an operating system that's also a sixty four

147
00:08:43,400 --> 00:08:46,120
Speaker 1: bit operating system if you wanted to run at that

148
00:08:46,240 --> 00:08:49,600
Speaker 1: full speed. Most sixty four bit systems are capable at

149
00:08:49,679 --> 00:08:54,839
Speaker 1: running thirty two bit UH software UM usually through either

150
00:08:55,559 --> 00:08:57,440
Speaker 1: UH there's like a there might be a thirty two

151
00:08:57,440 --> 00:09:00,839
Speaker 1: bit core that's incorporated in the TOM itself, or it

152
00:09:00,920 --> 00:09:03,960
Speaker 1: might be that there's an emulator running. But usually a

153
00:09:04,000 --> 00:09:06,360
Speaker 1: sixty four bit system is capable of running thirty two

154
00:09:06,400 --> 00:09:10,160
Speaker 1: bits software. If it weren't, then you would rapidly discover

155
00:09:10,280 --> 00:09:14,080
Speaker 1: that most software would be unusable because not not everyone

156
00:09:14,120 --> 00:09:16,880
Speaker 1: has upgraded up to sixty four bit yet. Before you

157
00:09:16,920 --> 00:09:18,719
Speaker 1: send us a list of all the software that you've

158
00:09:18,760 --> 00:09:20,720
Speaker 1: tried on your sixty four bit system that doesn't work,

159
00:09:20,760 --> 00:09:23,600
Speaker 1: remember your mileage may vary. Some restrictions apply. It also

160
00:09:23,640 --> 00:09:26,920
Speaker 1: depends heavily upon the actual operating system and how it

161
00:09:27,000 --> 00:09:29,480
Speaker 1: was providing that support. Because again, if you're talking about

162
00:09:29,520 --> 00:09:33,000
Speaker 1: emulators that does that's not a one size fits all approach,

163
00:09:33,360 --> 00:09:36,600
Speaker 1: you know, So go ahead. I was gonna say, here's

164
00:09:36,600 --> 00:09:40,160
Speaker 1: the interesting part about the thirty two bit versus sixty

165
00:09:40,160 --> 00:09:45,040
Speaker 1: four bit systems. Thirty two bit systems can only address

166
00:09:45,559 --> 00:09:47,840
Speaker 1: a certain amount well, all of them can address a

167
00:09:47,840 --> 00:09:53,480
Speaker 1: certain amount of computer memory of RAM, And with thirty

168
00:09:53,520 --> 00:09:58,640
Speaker 1: two bit systems, you can only address for gigabytes of RAM,

169
00:09:58,679 --> 00:10:03,840
Speaker 1: and back in the day, everyone thought four gigabytes a RAM, Wow,

170
00:10:04,160 --> 00:10:08,040
Speaker 1: we'll never need that much. That that famous quote attributed

171
00:10:08,080 --> 00:10:12,199
Speaker 1: to Bill Gates, which apparently he never said about how much.

172
00:10:12,440 --> 00:10:15,760
Speaker 1: I forgotten how much it was, like megabytes or something

173
00:10:15,760 --> 00:10:20,000
Speaker 1: like that. But um, but yeah, people said, well, that's

174
00:10:20,040 --> 00:10:22,400
Speaker 1: that's plenty for what we do. But the thing about

175
00:10:22,440 --> 00:10:25,520
Speaker 1: it is, now we're using computers to do high end

176
00:10:25,559 --> 00:10:30,800
Speaker 1: graphics work and high end soundwork. Um, scientific calculations, scientific calculations.

177
00:10:30,800 --> 00:10:36,280
Speaker 1: We expect our game machines to render beautiful three D

178
00:10:36,520 --> 00:10:39,840
Speaker 1: graphics where where the hair on people's heads moves with

179
00:10:39,880 --> 00:10:43,079
Speaker 1: the breeze and the leaves, there's no clipping or effect.

180
00:10:43,120 --> 00:10:46,040
Speaker 1: It doesn't affect the physics engine at all. Yeah. Yeah,

181
00:10:46,080 --> 00:10:49,959
Speaker 1: And the thing is, at a certain point, uh, you're

182
00:10:50,000 --> 00:10:52,439
Speaker 1: you're kind of looking for more from the system because

183
00:10:53,080 --> 00:10:57,760
Speaker 1: we're able to do these things now. So they've enabled processors,

184
00:10:57,800 --> 00:11:01,040
Speaker 1: and these sixty four bit processors are not brand new.

185
00:11:01,120 --> 00:11:03,840
Speaker 1: They didn't come out in These have been on the

186
00:11:03,880 --> 00:11:07,360
Speaker 1: market for for several years and in fact, the earliest

187
00:11:07,360 --> 00:11:11,359
Speaker 1: ones date from the seventies. Yeah. Yeah, the Kraze supercomputer,

188
00:11:11,400 --> 00:11:15,839
Speaker 1: the original kraz one supercomputer had a sixty four bit architecture. Yes, so,

189
00:11:15,920 --> 00:11:19,679
Speaker 1: while um so, while thirty two bit machines can address

190
00:11:20,760 --> 00:11:24,240
Speaker 1: for gigabytes of RAM, a sixty four bit machine and

191
00:11:24,280 --> 00:11:26,880
Speaker 1: this sort of sounds like our I p v six

192
00:11:27,040 --> 00:11:33,439
Speaker 1: thing can address seventeen point two billion gigabytes of RAM,

193
00:11:33,600 --> 00:11:36,800
Speaker 1: which is far more than any of our machines will

194
00:11:36,840 --> 00:11:39,360
Speaker 1: hold at this point. Now, I've seen machines that will

195
00:11:39,400 --> 00:11:43,200
Speaker 1: hold sixty four gigabytes of RAM. They're probably some really

196
00:11:43,240 --> 00:11:45,440
Speaker 1: high end machines that will hold even more than that,

197
00:11:45,800 --> 00:11:49,800
Speaker 1: but it's still far more than the operating system and

198
00:11:50,480 --> 00:11:55,000
Speaker 1: computer hardware can access right now. So basically, this is

199
00:11:55,040 --> 00:11:58,640
Speaker 1: a build for the future, the immediate foreseeable future, and

200
00:11:58,640 --> 00:12:01,880
Speaker 1: the more. Um. If you've ever heard somebody say, hey,

201
00:12:01,920 --> 00:12:03,760
Speaker 1: I know, if you really want to speed up your computer,

202
00:12:04,240 --> 00:12:06,400
Speaker 1: a cheap way to do that is to add more RAM. Well,

203
00:12:06,440 --> 00:12:09,319
Speaker 1: in general that's true. If you have more memory space,

204
00:12:09,360 --> 00:12:13,480
Speaker 1: that gives your computer a lot more room to handle uh,

205
00:12:13,800 --> 00:12:17,440
Speaker 1: regular calculations, because keep in mind that your operating system

206
00:12:17,520 --> 00:12:19,640
Speaker 1: is taking up a certain amount of RAM and all

207
00:12:19,679 --> 00:12:23,720
Speaker 1: the other operating stuff under the UM that that's hanging

208
00:12:23,760 --> 00:12:27,640
Speaker 1: out with it, like say um virus protection software and

209
00:12:27,679 --> 00:12:29,320
Speaker 1: other things that you use on a daily basis, and

210
00:12:29,320 --> 00:12:33,000
Speaker 1: then you open up Photoshop to work on on stuff

211
00:12:33,000 --> 00:12:36,480
Speaker 1: and it runs incredibly slow. And why, oh man, why

212
00:12:36,480 --> 00:12:39,079
Speaker 1: does this run so slow? Well, if it had more memory,

213
00:12:39,440 --> 00:12:41,920
Speaker 1: it would be far easier for the computer to allocate

214
00:12:42,000 --> 00:12:46,320
Speaker 1: and resources to Photoshop because it's already got a bunch

215
00:12:46,320 --> 00:12:48,560
Speaker 1: of stuff in memory. So yeah, it's it's it's both

216
00:12:48,600 --> 00:12:52,080
Speaker 1: the processor speed itself and the speed at which it

217
00:12:52,080 --> 00:12:54,240
Speaker 1: can or the amount of memory it can access a

218
00:12:54,280 --> 00:12:56,440
Speaker 1: think of a huge difference. Yeah, think of it this way,

219
00:12:56,520 --> 00:13:01,719
Speaker 1: like your your computer. If if you're processor had to

220
00:13:02,760 --> 00:13:05,480
Speaker 1: access your hard drive every time you need to pull

221
00:13:05,559 --> 00:13:09,240
Speaker 1: up information, it would slow everything down, right, Like if

222
00:13:09,280 --> 00:13:11,640
Speaker 1: it had to go into your hard drive in order

223
00:13:11,640 --> 00:13:14,960
Speaker 1: to pull whatever the information is in order to execute

224
00:13:15,000 --> 00:13:17,120
Speaker 1: the file you just said, or the execute the command

225
00:13:17,160 --> 00:13:20,719
Speaker 1: you just made, then it would slow things down to

226
00:13:20,840 --> 00:13:24,079
Speaker 1: a crawl. So if you were playing a game, for example,

227
00:13:24,160 --> 00:13:28,040
Speaker 1: and you press the jump button and the and so

228
00:13:28,120 --> 00:13:31,040
Speaker 1: you've you've executed the command. You've pressed the button that's

229
00:13:31,080 --> 00:13:34,040
Speaker 1: going to cause your character to jump. Apparently that character

230
00:13:34,080 --> 00:13:39,600
Speaker 1: is Mario, then the jump man. The computer will then

231
00:13:39,640 --> 00:13:41,800
Speaker 1: take that command, it would have to search your hard

232
00:13:41,880 --> 00:13:45,280
Speaker 1: drive to find out all right, I've been given this command,

233
00:13:45,320 --> 00:13:48,000
Speaker 1: here's the sub parameters that the game is in right now.

234
00:13:48,360 --> 00:13:51,880
Speaker 1: What happens next? It would get that information, process it,

235
00:13:51,920 --> 00:13:53,640
Speaker 1: and then send it back to you, and this would

236
00:13:53,679 --> 00:13:56,280
Speaker 1: take a long time. RAM what it does is it

237
00:13:56,320 --> 00:13:59,520
Speaker 1: allows you allows the computer to pull the essentially the

238
00:13:59,520 --> 00:14:02,040
Speaker 1: most pertinent information to whatever is going on right then

239
00:14:02,080 --> 00:14:05,679
Speaker 1: and there to be in a temporary storage space so

240
00:14:05,720 --> 00:14:09,040
Speaker 1: that the processor doesn't have to access the hard drive

241
00:14:09,320 --> 00:14:12,240
Speaker 1: in order to load stuff. It just accesses RAM. And

242
00:14:12,280 --> 00:14:15,160
Speaker 1: that's much faster because you know the RAM is just

243
00:14:15,200 --> 00:14:17,760
Speaker 1: going to be there for the duration of the instance

244
00:14:17,800 --> 00:14:21,720
Speaker 1: that you're on, like until you shut your computer down. UM.

245
00:14:21,880 --> 00:14:24,480
Speaker 1: This is also why if you're playing a game on

246
00:14:24,520 --> 00:14:27,000
Speaker 1: a console and you get to a new level and

247
00:14:27,080 --> 00:14:30,240
Speaker 1: you get that loading screen, well, essentially it's loading that

248
00:14:30,520 --> 00:14:34,560
Speaker 1: information into the consoles RAMS so that when you're playing

249
00:14:34,800 --> 00:14:37,280
Speaker 1: it doesn't have to refer back to the hard drive

250
00:14:37,400 --> 00:14:40,880
Speaker 1: and and that would impact your experience. So that's the

251
00:14:40,880 --> 00:14:42,960
Speaker 1: same sort of idea. And now with the sixty four

252
00:14:43,000 --> 00:14:46,200
Speaker 1: bit system, what you've done is dramatically increase the amount

253
00:14:46,200 --> 00:14:50,600
Speaker 1: of RAM your system can potentially have, which means the

254
00:14:50,720 --> 00:14:53,160
Speaker 1: CPU will not have to go back to the hard

255
00:14:53,240 --> 00:14:56,120
Speaker 1: drive as frequently. Yeah, and the thing is, I mean

256
00:14:56,360 --> 00:14:58,640
Speaker 1: load more information all at one time. Sorry, no, no,

257
00:14:58,720 --> 00:15:02,400
Speaker 1: I'm sorry. I didn't realize, but my brain clicked. I

258
00:15:02,440 --> 00:15:04,680
Speaker 1: had to go back to hard drive space. I see,

259
00:15:04,760 --> 00:15:08,400
Speaker 1: I see where we should increase your RAM. So, um,

260
00:15:08,440 --> 00:15:13,480
Speaker 1: I've been trying well, um, and and this is great.

261
00:15:13,560 --> 00:15:15,680
Speaker 1: You know. Of course, you can always speed stuff up

262
00:15:15,680 --> 00:15:20,600
Speaker 1: by closing things that you're not using, you know, but uh, this,

263
00:15:20,680 --> 00:15:24,080
Speaker 1: this presents a real advantage for people who are are

264
00:15:24,280 --> 00:15:26,680
Speaker 1: doing things that are memory heavy, or people who need

265
00:15:26,720 --> 00:15:29,200
Speaker 1: to keep multiple programs open. Say you're editing an article

266
00:15:29,240 --> 00:15:32,440
Speaker 1: and you have your word processor and your graphics programs.

267
00:15:32,440 --> 00:15:34,520
Speaker 1: You can do the photos that go along with the article,

268
00:15:34,560 --> 00:15:36,960
Speaker 1: and you have your email open. I've got it to

269
00:15:37,040 --> 00:15:39,960
Speaker 1: do list already. You don't have to drive at home

270
00:15:40,120 --> 00:15:41,880
Speaker 1: like that. But yeah, I mean you're working on all

271
00:15:41,880 --> 00:15:45,280
Speaker 1: those things simultaneously. If you have enough RAM, you should

272
00:15:45,280 --> 00:15:47,040
Speaker 1: be able to work fairly quickly as you as you

273
00:15:47,080 --> 00:15:49,760
Speaker 1: go from one back and forth, you know, to the other.

274
00:15:50,040 --> 00:15:53,360
Speaker 1: Because it's already loaded into RAM, the computer doesn't have

275
00:15:53,400 --> 00:15:56,520
Speaker 1: to go and search for stuff. So let's use Let's

276
00:15:56,600 --> 00:15:59,120
Speaker 1: use my home computer as an example. UM. It's about

277
00:15:59,120 --> 00:16:01,720
Speaker 1: three years old at the time we're recording this UM,

278
00:16:01,760 --> 00:16:05,760
Speaker 1: and it has a physical memory capacity of four gigabytes

279
00:16:05,760 --> 00:16:08,120
Speaker 1: of RAM. Now I have an operating system that will

280
00:16:08,200 --> 00:16:11,200
Speaker 1: run in either thirty two bit or sixty four bit mode.

281
00:16:11,840 --> 00:16:14,760
Speaker 1: The question is should I boot into sixty four bit

282
00:16:14,800 --> 00:16:16,720
Speaker 1: mode or should I just default to thirty two bit

283
00:16:18,400 --> 00:16:20,640
Speaker 1: depending on what you're using. Actually, i'd say just default

284
00:16:20,680 --> 00:16:24,200
Speaker 1: the thirty two bit because it won't even I can't

285
00:16:24,240 --> 00:16:27,520
Speaker 1: even take advantage of the sixty four bit advantage of

286
00:16:27,760 --> 00:16:30,600
Speaker 1: being able to address more RAM because I don't even

287
00:16:30,600 --> 00:16:33,240
Speaker 1: have the capacity for more than four gigabytes and RAM.

288
00:16:33,560 --> 00:16:36,120
Speaker 1: It doesn't make any sense to do that. But UM,

289
00:16:36,160 --> 00:16:39,200
Speaker 1: and you can have a top ended machine, but if

290
00:16:39,200 --> 00:16:42,360
Speaker 1: you're running an older operating system on it that won't

291
00:16:42,640 --> 00:16:45,560
Speaker 1: run in sixty four bit mode, you're not able to

292
00:16:45,560 --> 00:16:48,040
Speaker 1: take advantage of it. So, as Jonathan pointed out earlier,

293
00:16:48,080 --> 00:16:50,520
Speaker 1: you have to have the machine, you have to have

294
00:16:50,800 --> 00:16:53,600
Speaker 1: more memory than for gigabytes, and you have to have

295
00:16:53,680 --> 00:16:58,440
Speaker 1: the operating system basically to take advantage of these benefits.

296
00:16:58,440 --> 00:17:01,280
Speaker 1: But if you do that will really help you out. Yeah, Like,

297
00:17:01,360 --> 00:17:03,920
Speaker 1: let's say that you want to do some heavy duty

298
00:17:04,040 --> 00:17:06,760
Speaker 1: video editing and and let's see you're working on a

299
00:17:06,760 --> 00:17:10,880
Speaker 1: feature link film. Well, the benefit to a sixty four

300
00:17:10,880 --> 00:17:12,720
Speaker 1: bit system is that you would be able to to

301
00:17:13,080 --> 00:17:17,360
Speaker 1: load a lot more footage in a single go than

302
00:17:17,400 --> 00:17:19,320
Speaker 1: you would if you had a thirty two bit system.

303
00:17:19,359 --> 00:17:22,119
Speaker 1: It would just be much faster, much more efficient. And

304
00:17:22,119 --> 00:17:26,359
Speaker 1: it's not again necessarily because the processor is faster. Now, grant,

305
00:17:26,400 --> 00:17:28,879
Speaker 1: a faster processor also helps things a lot. And then

306
00:17:28,920 --> 00:17:32,160
Speaker 1: we've talked in the past a bit about multi core processors,

307
00:17:32,240 --> 00:17:36,960
Speaker 1: which uh seem to give seem to be faster, even

308
00:17:36,960 --> 00:17:39,400
Speaker 1: though if you look at the processor speeds, they may

309
00:17:39,400 --> 00:17:42,159
Speaker 1: not be that much faster than a single core processor.

310
00:17:42,200 --> 00:17:46,639
Speaker 1: In that case, the reason why it's it's uh working

311
00:17:46,680 --> 00:17:50,200
Speaker 1: a more efficiently is because it's dividing up computer problems

312
00:17:50,200 --> 00:17:53,040
Speaker 1: into segments, and each core works on a segment of

313
00:17:53,080 --> 00:17:56,160
Speaker 1: the problem and then it ends up being put together

314
00:17:56,240 --> 00:17:58,640
Speaker 1: kind of like a puzzle in the end. And that's

315
00:17:58,680 --> 00:18:01,400
Speaker 1: what the you know, that's why a multi core will

316
00:18:01,440 --> 00:18:04,480
Speaker 1: work best for certain kinds of problems. Again, just like

317
00:18:04,800 --> 00:18:06,720
Speaker 1: we were talking about with the sixty four bit versus

318
00:18:06,720 --> 00:18:10,480
Speaker 1: thirty two bit, a multi core processor isn't necessarily going

319
00:18:10,520 --> 00:18:14,960
Speaker 1: to execute every single application at a faster speed than

320
00:18:15,640 --> 00:18:19,480
Speaker 1: a comparable single core processor because some just don't. Some

321
00:18:19,520 --> 00:18:23,440
Speaker 1: problems just don't break down into components. Uh. The ones

322
00:18:23,480 --> 00:18:26,960
Speaker 1: that do we call parallel problems. And uh, in in

323
00:18:27,160 --> 00:18:30,199
Speaker 1: case of grid computing, when you're talking about things like

324
00:18:30,800 --> 00:18:36,640
Speaker 1: folding proteins, you call them embarrassingly parallel problems. I'm sorry,

325
00:18:36,720 --> 00:18:39,720
Speaker 1: didn't mean to bring up the subject. But anyway, Uh,

326
00:18:39,920 --> 00:18:46,959
Speaker 1: that's that's a that's another key element to computer speeds. So, yeah,

327
00:18:47,200 --> 00:18:50,720
Speaker 1: sixty four bit operating systems. When when Windows came out

328
00:18:50,760 --> 00:18:53,520
Speaker 1: with Windows Vista for six or four bit Windows Vista,

329
00:18:54,000 --> 00:18:56,280
Speaker 1: there were some problems. Okay, first of all, there were

330
00:18:56,280 --> 00:19:01,760
Speaker 1: problems with within Windows Vista, right, that operating system got

331
00:19:01,800 --> 00:19:04,680
Speaker 1: a really bad name pretty quickly because there were a

332
00:19:04,760 --> 00:19:09,520
Speaker 1: lot of name Oh I'm sorry, I'm just saying that

333
00:19:09,560 --> 00:19:14,200
Speaker 1: they had a reputation for being not the best operating system.

334
00:19:14,240 --> 00:19:17,199
Speaker 1: There were a lot of features that people didn't care for,

335
00:19:17,359 --> 00:19:19,520
Speaker 1: and there were a lot of problems with its supporting

336
00:19:19,560 --> 00:19:22,560
Speaker 1: certain kinds of software versus not supporting other kinds. And

337
00:19:22,600 --> 00:19:27,040
Speaker 1: it's not yeah, right, so but the sixty four bit

338
00:19:27,080 --> 00:19:29,520
Speaker 1: system when it came out, there were even more problems,

339
00:19:29,560 --> 00:19:31,040
Speaker 1: and part of it was because it was, you know,

340
00:19:31,080 --> 00:19:35,600
Speaker 1: fairly young for the personal computing era. Against sixty four

341
00:19:35,640 --> 00:19:38,360
Speaker 1: bit architecture had been around for for more than a decade,

342
00:19:38,920 --> 00:19:42,040
Speaker 1: but but the actual use of it in personal computers

343
00:19:42,080 --> 00:19:45,560
Speaker 1: was pretty much brand new when the sixty four bit

344
00:19:45,560 --> 00:19:50,360
Speaker 1: Windows Vista version came out. Since then, we've seen computer

345
00:19:50,440 --> 00:19:55,080
Speaker 1: engineers really kind of optimized operating systems for sixty four bit,

346
00:19:55,600 --> 00:19:59,320
Speaker 1: so it's not as big a problem now. Unix had

347
00:19:59,320 --> 00:20:01,679
Speaker 1: a leg up a are pretty much everybody else on

348
00:20:01,720 --> 00:20:05,200
Speaker 1: that one. But now we're seeing it with other systems,

349
00:20:05,240 --> 00:20:10,919
Speaker 1: not just not just Unix or or its variants. So

350
00:20:12,119 --> 00:20:15,199
Speaker 1: should you go out and buy a sixty four bit system,

351
00:20:15,400 --> 00:20:20,640
Speaker 1: My suggestion would be unless your depends. Yeah, unless you're

352
00:20:20,680 --> 00:20:24,680
Speaker 1: really working with some heavy duty videos software, you're doing

353
00:20:24,680 --> 00:20:28,080
Speaker 1: scientific calculations, or you just want the most screaming video

354
00:20:28,160 --> 00:20:31,640
Speaker 1: games ever made, you probably don't need to worry about

355
00:20:31,680 --> 00:20:33,560
Speaker 1: it too much. Because the thing about video game machines

356
00:20:33,640 --> 00:20:36,720
Speaker 1: is often you do have a dedicated graphics processor, which

357
00:20:36,720 --> 00:20:38,720
Speaker 1: takes a lot of the helps. Yeah, it takes a

358
00:20:38,720 --> 00:20:42,040
Speaker 1: lot of the weight off of your CPU, although you

359
00:20:42,280 --> 00:20:46,680
Speaker 1: then have to add weight with a cooling system. Um.

360
00:20:46,720 --> 00:20:48,400
Speaker 1: But yeah, I would say that a sixty four bit

361
00:20:48,440 --> 00:20:52,920
Speaker 1: system probably is not necessary for most people right now. Now,

362
00:20:53,040 --> 00:20:57,560
Speaker 1: over time, as the the whole all the parts get

363
00:20:57,640 --> 00:21:01,480
Speaker 1: cheaper than the operating systems will become or standardized. We'll

364
00:21:01,480 --> 00:21:04,280
Speaker 1: probably see sixty four bit become the news standard. And

365
00:21:04,320 --> 00:21:06,560
Speaker 1: in that case it won't be a question of sixty

366
00:21:06,560 --> 00:21:09,000
Speaker 1: four versus thirty two. It will be sixty four bit

367
00:21:09,080 --> 00:21:10,680
Speaker 1: is what's in the store, so that's what you get.

368
00:21:11,280 --> 00:21:14,640
Speaker 1: But right now, if you're shopping around, uh, just keep

369
00:21:14,640 --> 00:21:18,000
Speaker 1: in mind that even though the number is bigger, it

370
00:21:18,040 --> 00:21:22,520
Speaker 1: doesn't necessarily mean you're going to experience. Uh, it doesn't

371
00:21:22,520 --> 00:21:25,040
Speaker 1: mean your computing computing experience is immediately going to be

372
00:21:25,080 --> 00:21:26,600
Speaker 1: twice as fast as what it used to be on

373
00:21:26,640 --> 00:21:30,040
Speaker 1: your old thirty two bit system. Yeah. Yeah, And um,

374
00:21:30,080 --> 00:21:34,480
Speaker 1: as far as one systems go, I mean, the thing

375
00:21:34,600 --> 00:21:37,840
Speaker 1: is for for home computing. Really, I don't think the

376
00:21:37,920 --> 00:21:40,880
Speaker 1: average person needs anything like that, or or will need

377
00:21:40,920 --> 00:21:43,240
Speaker 1: anything like that for quite some time. If you're trying

378
00:21:43,240 --> 00:21:46,119
Speaker 1: to give sentience to your refrigerator, you may need a

379
00:21:46,200 --> 00:21:49,199
Speaker 1: hundred and twenty eight system for something like you know,

380
00:21:49,280 --> 00:21:52,640
Speaker 1: high end scientific computing. Well, sure, you know, super computer

381
00:21:52,720 --> 00:21:56,639
Speaker 1: type stuff. If you're searching for intelligent life, possibly in

382
00:21:56,680 --> 00:22:02,920
Speaker 1: this office, that joke is coming. Uh no, but yeah,

383
00:22:02,960 --> 00:22:05,080
Speaker 1: I mean when you when you're already able to address

384
00:22:05,680 --> 00:22:10,000
Speaker 1: seventeen exabytes of memory and you can't even fit that

385
00:22:10,080 --> 00:22:14,280
Speaker 1: inside the box. Yeah, there's no way to the memory

386
00:22:14,320 --> 00:22:17,400
Speaker 1: because the Yeah, you would have to have a computer

387
00:22:17,560 --> 00:22:21,160
Speaker 1: the size of well, the old ones because and I'm

388
00:22:21,160 --> 00:22:23,040
Speaker 1: not talking about the old computers. I'm talking about the

389
00:22:23,080 --> 00:22:25,879
Speaker 1: fictional Cathulu gods, the old ones. You have to have

390
00:22:25,880 --> 00:22:29,320
Speaker 1: a computer that size, so large that would rip the

391
00:22:29,359 --> 00:22:34,040
Speaker 1: sanity from your mind. Perhaps less scary, but depends on

392
00:22:34,080 --> 00:22:36,360
Speaker 1: what it's running. Yeah. So I mean this is it's

393
00:22:36,359 --> 00:22:38,199
Speaker 1: sort of again like the I p V six thing.

394
00:22:38,240 --> 00:22:39,560
Speaker 1: This is the kind of thing that's going to get

395
00:22:39,640 --> 00:22:43,320
Speaker 1: us through a long time. We will the the average

396
00:22:43,359 --> 00:22:45,640
Speaker 1: person is not going to need to worry about this

397
00:22:45,720 --> 00:22:49,840
Speaker 1: again anytime. Yeah. Now we say a long time, but

398
00:22:49,960 --> 00:22:55,480
Speaker 1: keep in mind, is computing a long time. Exactly five

399
00:22:55,560 --> 00:22:58,280
Speaker 1: years is a long time in computing terms. I just

400
00:22:58,280 --> 00:23:00,199
Speaker 1: wanted to make that clear before we had people right

401
00:23:00,240 --> 00:23:03,280
Speaker 1: in Well, I still remember, you know, talking about RAM

402
00:23:03,280 --> 00:23:06,240
Speaker 1: being a cheap way to upgrade your computer. Um, I

403
00:23:06,280 --> 00:23:09,439
Speaker 1: can buy another two gigabyte chip and pull out the

404
00:23:09,480 --> 00:23:11,960
Speaker 1: one that's in the available slot. I've got now to

405
00:23:12,080 --> 00:23:14,439
Speaker 1: upgrade to a full four. I've got three. I've got

406
00:23:14,480 --> 00:23:16,360
Speaker 1: two slots in mine, and it came with to one

407
00:23:16,359 --> 00:23:18,480
Speaker 1: gigabyte RAM sticks. I pulled one out and put it

408
00:23:18,520 --> 00:23:20,160
Speaker 1: two in there, and I could do the other one

409
00:23:20,200 --> 00:23:22,879
Speaker 1: for I think last time I looked twenty six or

410
00:23:22,920 --> 00:23:26,359
Speaker 1: thirty dollar or something like that. I remember buying a

411
00:23:26,400 --> 00:23:30,320
Speaker 1: two hundred and fifty six megabyte RAM chip for about

412
00:23:30,320 --> 00:23:37,159
Speaker 1: a dollar a meg so, so it cost the memory

413
00:23:37,200 --> 00:23:40,320
Speaker 1: has has decreased dramatically, and that was probably about fifteen

414
00:23:40,400 --> 00:23:42,760
Speaker 1: years ago. So you know, when we get to the

415
00:23:42,800 --> 00:23:46,360
Speaker 1: point where, uh we're talking about exitbytes of memory, it'll

416
00:23:46,400 --> 00:23:50,080
Speaker 1: probably be you know, yeah, it'll be a while, but

417
00:23:50,400 --> 00:23:52,880
Speaker 1: you know, memory will probably be so inexpense, at least

418
00:23:52,880 --> 00:23:55,920
Speaker 1: at that point by the recording of this podcast. So

419
00:23:56,240 --> 00:23:58,359
Speaker 1: it be so funny if this podcast went live and

420
00:23:58,400 --> 00:24:01,960
Speaker 1: I'm like, hey, did you get your out of teen xavitem,

421
00:24:02,960 --> 00:24:04,600
Speaker 1: because I've got mine. You have to you have to

422
00:24:04,600 --> 00:24:09,320
Speaker 1: bite in one ex sticks, so you've only got five slots.

423
00:24:09,440 --> 00:24:13,760
Speaker 1: Each stick is about five miles long. Yeah, so the yeah,

424
00:24:13,800 --> 00:24:15,760
Speaker 1: I mean we've got that. That's another good point. Actually,

425
00:24:15,800 --> 00:24:19,240
Speaker 1: it's the physical limitation of what we can build right now. Yeah,

426
00:24:19,560 --> 00:24:22,280
Speaker 1: that's that's the thing is that these chips do take

427
00:24:22,359 --> 00:24:25,840
Speaker 1: up physical space. So you know, for you to cram

428
00:24:25,880 --> 00:24:28,000
Speaker 1: more memory, you can't just I mean, there's not like

429
00:24:28,640 --> 00:24:30,720
Speaker 1: there's not like a switch that you click and you're like,

430
00:24:30,720 --> 00:24:33,200
Speaker 1: suddenly you've got more memory. You have to build those chips,

431
00:24:33,240 --> 00:24:36,399
Speaker 1: and the chips do get larger as you need more memory.

432
00:24:36,480 --> 00:24:38,800
Speaker 1: So because there's only a certain point at which the

433
00:24:38,840 --> 00:24:43,240
Speaker 1: physical you can store information in the physical architecture of

434
00:24:43,280 --> 00:24:47,160
Speaker 1: memory right now. Before that that we have advances going.

435
00:24:47,800 --> 00:24:50,440
Speaker 1: You know, there are advances in that every single year.

436
00:24:50,880 --> 00:24:53,560
Speaker 1: Just like Moore's law talks about the number of transistors

437
00:24:53,560 --> 00:24:55,879
Speaker 1: on the chip, that also applies to things like memory.

438
00:24:56,440 --> 00:25:00,280
Speaker 1: But uh, you know, we're nowhere near being will have

439
00:25:00,280 --> 00:25:03,360
Speaker 1: been an exit by a memory on a square inch

440
00:25:03,480 --> 00:25:07,840
Speaker 1: chip unless it's unless it's significantly tall. So that that,

441
00:25:07,880 --> 00:25:11,160
Speaker 1: I guess would be the last um of my suggestions.

442
00:25:11,160 --> 00:25:13,080
Speaker 1: If you're looking at the difference between a thirty two

443
00:25:13,119 --> 00:25:14,840
Speaker 1: and sixty four, if you can afford a sixty four

444
00:25:14,840 --> 00:25:17,320
Speaker 1: bit system, you're ready to upgrade, you might as well

445
00:25:17,359 --> 00:25:21,280
Speaker 1: go ahead and do it, because you'll be It's not

446
00:25:21,359 --> 00:25:24,400
Speaker 1: like you, I mean you have to worry about the

447
00:25:24,440 --> 00:25:30,160
Speaker 1: one uh systems systems coming out next year. Yeah, that's

448
00:25:30,520 --> 00:25:33,360
Speaker 1: you know, you can you could feel comfortable knowing that

449
00:25:33,720 --> 00:25:36,080
Speaker 1: this is something that will last you some your future,

450
00:25:36,160 --> 00:25:40,200
Speaker 1: proofing yourself to an extent, although again, as the components

451
00:25:40,240 --> 00:25:42,840
Speaker 1: get more advanced, you may have to You know, if

452
00:25:42,840 --> 00:25:45,440
Speaker 1: you're comfortable with the idea of popping open your computer

453
00:25:45,600 --> 00:25:48,879
Speaker 1: and switching stuff out occasionally, then it shouldn't be a

454
00:25:48,880 --> 00:25:52,080
Speaker 1: big deal. And the operating systems we had for a

455
00:25:52,080 --> 00:25:55,080
Speaker 1: while for the last few years have been sixty four

456
00:25:55,160 --> 00:26:01,080
Speaker 1: bit capable and on basically everything Lennox, Mac, Windows, So um,

457
00:26:01,119 --> 00:26:02,919
Speaker 1: you know it might be in your advantage to your

458
00:26:02,920 --> 00:26:06,520
Speaker 1: advantage to upgrade. Yep. So I guess that wraps up

459
00:26:06,520 --> 00:26:10,840
Speaker 1: this discussion. Hey guess what what this episode is is

460
00:26:11,040 --> 00:26:14,119
Speaker 1: gonna come in under thirty minutes. Really, it's like the

461
00:26:14,160 --> 00:26:16,640
Speaker 1: first one in Ages, right, But it was a nice

462
00:26:17,080 --> 00:26:19,719
Speaker 1: simple topic to tackle, and it was good for us

463
00:26:19,760 --> 00:26:22,440
Speaker 1: to kind of get into that whole architecture thing because

464
00:26:22,480 --> 00:26:24,439
Speaker 1: I think a lot of people are kind of confused

465
00:26:24,480 --> 00:26:27,160
Speaker 1: by this. And again, when you hear numbers, you immediately

466
00:26:27,240 --> 00:26:30,240
Speaker 1: think the bigger number is automatically better in all cases,

467
00:26:30,320 --> 00:26:32,920
Speaker 1: and it's not always. That's not always the case. It's

468
00:26:32,920 --> 00:26:36,879
Speaker 1: also interesting that it sounds complex, but it's remarkably simple

469
00:26:36,880 --> 00:26:38,760
Speaker 1: really when you get down to it. Yeah, once you

470
00:26:38,800 --> 00:26:42,040
Speaker 1: get it, once you start thinking about those buildings. Yeah. Alright,

471
00:26:42,080 --> 00:26:44,600
